'4 Claims.

This invention relates to anti-vibration machinery bases and relates moreparticularly to machinery bases of the class described which can be readily constructed in the field from standard structural shapes.

In the construction of anti-vibration machinery bases, it is desirable to ship stock resilient units to a customer who then constructs the machinery base around the resilient units from structural steel members secured locally. It is desirable to construct these resilient units so that they can be readily removed from the machinery base without disturbing the remaining resilient units, thus permitting the resilient units removed to be inspected and repaired from time to time.

An object of this invention therefore is to provide resilient units which may be shipped to the customer and built into a machinery base from structural steel members obtained locally.

Another object of the invention is to provide a machinery base in which the resilient units can be easily removed for inspection and repair without stopping the operation of the machine; also to improve machinery bases in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which Fig. 1 is a perspective view of one of the resilient units embodying the present invention,

Fig. 2 is a plan view of the assembled machinery base,

Fig. 3 is a sectional elevation through the completed machinery base taken on line 3-3 of Fig. 2,

Fig. 4 is an elevation, partly in section, of a modified form of machinery base suitable for supporting heavy machinery, and v Fig. 5 is a sectional elevation through the machinery base shown in Fig. 4.

One of the resilient units as shown in Fig. 1 comprises a base plate Ill having apertures H for receiving bolts l2 which secure said plate to a metal strip l3. A floor I4 supports the plate l3, suitable cementitious grouting material l5 intervening between the floor I4 and strip l3. A plurality of resilient fiat springs l6 are provided with a pair of spaced resilient loops I! connected by a saddle member i8. Outstanding legs l9 are formed on the loops i1 and are secured to the plate I0 as by bolts or rivets 20. A bracket 2| has a depending rib 22 which rests upon the saddle member l8 and are secured thereto by rivets 23. A reinforcing plate 24 is secured to the bracket 2| by a bolt 25., Spaced angle strips exterior appearance.

26 are secured to the outer edges of bracket 2| as by welding. Upstanding flanges 21 are formed on the strips 26 and are secured by bolts 28 to the webs of spaced channels 29 and 30 which form )7 the framework of the machinery platform. The 5 flanges 21 may becast integrally with the brackets 2! if so desired. The ends of the channels 23 and 30 are secured together by angle attaching clips 3| in the manner shown in Fig. 2 so that spaced channels extend entirely around the periphery of 10 the machinery base.

The inner channels 23 have inwardly extending upper flanges 32 and lower flanges 33. Form boards 34 are laid across the flanges 33, and a cementitious platform 35 is formed on top of the 15 boards 34, said platform having anchoring bolts 36 embedded therein for firmly anchoring a vibrating machine 31. A shield 38 extends on top of the channels 23 and 30 resting on flanges 32 and upper flanges 39 formed on the channels 34, 20 said shield being removably attached to the flange 39 by a bolt 40. A depending flange 4| on shield 38 conceals the channels 30 and presentsa finished When it becomes necessary to remove a resilient unit for inspection or 25 repair, bolt 40 and shield 38 is removed. Bolts l2 and 28 are then removed and the resilient unit is removed vertically from the frame without disturbing the remaining resilient units or stopping the machine 31. The vertical removal of the 30 resilient units greatly facilitates the operation of making replacements of the resilient units.

For resiliently supporting extremely heavy machinery, it is desirable to use the structure shown in Figs. 4 and 5 in which vertical standards 43 have their lower ends resting directly upon steel beams 44 forming the framework of the building. A concrete floor slab 45 also rests upon the beams 44 and embeds the lower ends of standards 43. Steel structural members '43 are secured to the upper ends of standards 43, being provided with suitable gusset plates 41. A plate 43 is supported on top of the beams 43 and resilient units 43 are supported on said plates 48. Spaced channels 53 are supported on the resilient units 49 in a manner similar to that previously described. A superstructure of beams 5| and 52 is supported on the channels 50 and forms a platform for supporting the vibrating machine 53. 50

I would state in conclusion that, while the illustrated examples constitute practical embodiments of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without 5 departing from thespirit of the invention as defined in the appended claims.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent:-

1. In a resilient machinery base, a pair of spaced structural members arranged around each of the sides of a polygon having at least four sides, the webs of said structural members extending vertically, resilient units each comprising a base to be removably secured to a supporting member and an upper bracket having spaced, vertically extending flanges, means for removably securing said flanges to said webs, and a machinery supporting platform extending horiaontally across the center of said polygon 2. In a resilient machinery base, a plurality of structural members arranged in spacedpairs around the periphery of a machinery platform, and a plurality of resilient units removably se cured between each pair of structural members; said units being connected to vertically extending parts on said members so as to be removable from said members by vertical movement for inspection and repair.

3. In a resilient machinery base, a plurality of structural members arranged inspaced pairs around a polygon having at least four sides, ver- 5 tically removable resilient units between said pairs of structural members, said units being secured to vertically extending parts on said members, inwardly extending lower flanges on the inner of said structural members, a form member laid across said flanges, and a cementitious machinery platform on said form member.

4. In a resilient machinery base, a plurality of structural members arranged in spaced pairs around the periphery of a machinery platform, a 1 plurality oi resilient units removably secured between vertical parts of each pair of structural members, said units being removable from said members for inspection and repair, by a vertical movement, and a shield removably secured across 20
